Ninja Disconnects my internet

[cipher4d]

For some reason ninjatrader keeps disconnecting the whole home network from the internet. To reconnect I turn off/on the router and modem. The reason I think NT is dropping the internet is because the internet has only dropped when NT has been running for 10-20 minutes.

I normally do not have this problem but for the past week I have been trading from a different location and the internet configuration does not seem to work favorably with NT.

I was wondering if NT support had any suggestions like port forwarding or some other router config. I am running AT&T Dynamic IP DSL and the trading computer is connected via ethernet cable.

Hello cipher 4D,

Thank you for your post.

We realize that lost connections can be frustrating. A connection state between NinjaTrader and your broker/market data vendor is not dictated by NinjaTrader. The NinjaTrader application only reports the connection state as it is reported by the API you are connected through. NinjaTrader behaves like a radio receiver in that it receives signals from the connected server. If the signals are not coming through, the underlying broker/market data vendor API reports this to the NinjaTrader application which in turn reports this back to you. Once a loss of connection is reported, NinjaTrader or the underlying API wil continuously try to re-establish a connection.
Common reasons that contribute to connection stability are:

• ISP issues
• Hardware firewall changing IP addresses frequently
• Dynamic IP addresses changing frequently intraday. Usually this happens once a week buy you may want to check with your ISP. If they do change daily, requesting a static IP address may help.
• With Windows XP SP2, if you have more than 10 open TCPIP socket connections (10 programs making socket connections through the internet) Windows will randomly shut down some connections
• Broker/market data servers may be experiencing temporary downtime

If you check the above list and use it as a guideline for troubleshooting issues regarding your internet connection, then it should be possible to remedy these lost connections.
